Definitions
- the embodiments disclosed herein relate generally to coke ovens, especially corbel structures associated with coke ovens.
- the corbel structures disclosed herein are formed of an assembly of monolithic refractory blocks.
- Coke ovens traditionally comprise massive refractory brick structures in which there are batteries of adjacent parallel walls made up from a large variety of differently shaped refractory bricks.
- the bricks must be able to withstand high temperatures and strong mechanical loading.
- the interior of the walls contains flue ducts, burners, flue gas control passages and the like.
- the detailed design of the oven is usually quite complicated in order to obtain the necessary heat distribution within the oven and gas flows through the walls.
- the coke oven corbel structures of the embodiments disclosed herein include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues.
- a first tier of refractory blocks in the assembly includes a series of lower cradle blocks defining respective lower semi-circular surfaces extending from one end to another end of the corbel structure.
- a second tier of the refractory blocks in the assembly includes a series of upper crown blocks defining respective upper semi-circular surfaces extending from one end to another end of the corbel structure.
- the second tier of refractory blocks is stacked on the first tier of refractory blocks so that the respective upper and lower semicircular surfaces of the upper crown blocks and lower cradle blocks thereof oppose one another to thereby define a cylindrical channel between opposed ends of the corbel structure.
- At least one set of the upper crown blocks in the second tier of refractory blocks defines respective substantially vertical segments of the vertically oriented central flues of the corbel structure, a lower end of the substantially vertical segments terminating at the upper semi-circular surface to thereby be in fluid communication with the cylindrical channel of the corbel structure.
- upper and lower end blocks may be provided at least at the one end of the corbel structure, wherein the upper and lower end blocks define opposed upper and lower rectangular U-shaped cradle surfaces.
- a transition gun block may thus be received within the U-shaped cradle surfaces of the upper and lower end blocks, in which case the transition gun block defines a gun block transition channel in fluid communication with the cylindrical channel defined by the upper and lower cradle blocks.
- the transition gun block may be in the form of a rectangular cuboid.
- the transition gun block may include upper and lower gun block sections defining opposed U-shaped surfaces to establish the gun block transition channel.
- Some embodiments of the corbel structure may include at least a second set of the upper crown blocks in the second tier of refractory blocks which defines respective diagonally oriented lateral flue segments of diagonally oriented lateral flues of the corbel structure. If present, the first and second sets of the upper crown blocks are
- a third tier of refractory blocks may be provided according to other embodiments, whereby the refractory blocks of the third tier are stacked on the second tier of refractory blocks.
- the third tier of refractory blocks may comprise a series of inverted T-shaped flue blocks.
- the inverted T-shaped flue blocks may be provided with upper and lower ledge surfaces. Lower spacer blocks having respective ends supported by the lower edges of the inverted T-shaped flue blocks may thus be provided in the third tier of refractory blocks.
- Some embodiments will include at least one set of the inverted T-shaped blocks in the third tier of refractory blocks which defines respective substantially vertical segments of the vertically oriented central flues of the corbel structure. A lower end of the substantially vertical segments may thus be aligned with an upper end of the substantially vertical segments of upper cradle blocks so as to be in fluid
- the substantially vertical segments of the at least one series of inverted T-shaped blocks may be U-shaped.
- the U- shaped substantially vertical segments according to such embodiments would thereby have an open end closed by a vertical face of an adjacent one of the inverted T-shaped blocks.
- At least a second set of the inverted T-shaped blocks in the third tier of refractory blocks defines respective diagonally oriented lateral flue segments of diagonally oriented lateral flues of the corbel structure.
- Certain embodiments of the corbel structure will include a fourth tier of refractory blocks comprised of a series of elongate shoulder blocks positioned in an end-to-end manner on upper ledge surfaces of the inverted T-shaped blocks of the third tier.
- Upper spacer blocks may thus be positioned adjacent to the shoulder blocks and stacked on the lower spacer blocks.
- a series of split cylindrical gun blocks may be positioned in the cylindrical channel of the corbel structure.
- the cylindrical gun blocks may comprise upper and lower semi- cylindrical gun block sections.
- Some embodiments will include an aperture defined by at least some of the upper semi-cylindrical gun block sections which is in fluid communication with respective ones of the substantially vertical segments of the at least one set of the upper crown blocks.

- the first tier 100 of the corbel structure 10 is provided with an interconnected series of cradle blocks 102 each defining a semi-cylindrical surface 104 extending longitudinally between the front and rear faces of each block.
- the semi-cylindrical surface 104 will therefore define a longitudinal U-shaped channel extending in a lengthwise direction of the corbel structure 10.
- An end block 106 is provided adjacent to a front face of the end-most one of the cradle blocks 102.
- the end block 106 defines a rectangular U-shaped cradle 106a for supporting a rectangular cuboid transition gun block 108 comprised of upper and lower gun block sections 108a, 108b.
- the gun block sections 108a, 108b define respective opposed semi-cylindrical surfaces which collectively establish a cylindrical channel 108c coaxially aligned with the U-shaped channel formed by the semi-cylindrical surfaces 104 of the cradle blocks 102.
- the second tier 200 of blocks comprising the corbel structure 10 is shown in FIGS. 10A and 10B.
- the second tier 200 is comprised of an alternating series of lateral flue crown blocks 202 and central flue crown blocks 204, the former defining a section of the diagonally oriented flues 72 and the latter defining a section of the substantially vertically oriented flues 60.
- the central flue blocks 204 define a substantially vertically oriented rectangular segment of the flue 60
- the lateral flue crown blocks 202 define a diagonally oriented U-shaped channel which is closed by a vertical face of an adjacent one of the blocks 204.
- the central flue blocks 204 may include a static gas nozzle 207 positioned in the segment of the flue 60 so as to control the flow of gas thereinto.
- An end block 206 is provided adjacent to a front face of the end-most one of the crown blocks 202.
- the end block 206 is provided with an inverted rectangular U-shaped cradle surface 206a to receive the upper gun block section 108a of the transition gun block 108.
- the end block 206 includes oppositely oriented mounting tongues 206b so as to mate with corresponding channel surfaces 208a associated with the wing blocks 208.
- the lateral wing blocks 208 are each horizontally split to form upper and lower wing block segments 208b, 208c, the latter having a U-shaped channel 208d which is closed by an opposed face of the upper wing block segment 208b.
- the third tier 300 of blocks forming the corbel structure 10 is depicted in FIG. 1 1 .
- the third tier 300 is comprised of an alternating series of inverted T-shaped lateral flue blocks 302 and inverted T-shaped central flue blocks 304, the former defining a section of the substantially vertically oriented flues 60 and the latter defining a section of the diagonally oriented flues 72.
- Lower spacer blocks 306 abut laterally against the side edges of the blocks 302, 304 and are supported by the upper lateral surfaces of the crown blocks 202, 204 of the subjacent second tier 200 of blocks.
- the blocks 302, 304 respectively define lower ledges 302a, 304a which are coplanar with the top surface of the lower spacer blocks 306.
- the upper spacer blocks 308 are thus supported by the lower spacer blocks 306 and have end portions which are received on the respective lower ledges 302a, 304a.
- An inverted T-shaped end block 306 is provided adjacent to a front face of the end-most one of the blocks 304.
- the end block 306 defines a ledge 306a which is coplanar with the ledges 302a, 304a of the blocks 302, 304, respectively.
- the fourth tier 400 of blocks forming the corbel structure 10 is depicted in FIG. 12.
- the fourth tier 400 includes a series of elongate shoulder blocks 402 positioned in an end-to-end manner on the upper ledge surfaces 302b, 304b of the blocks 302, 304, respectively, of the third tier 300 (see FIG. 1 1 ).
- a T-shaped end block 406 is positioned on the top surface of the end block 306 of the third tier 300. Spacer blocks 406 are laid onto the spacer blocks 308 of the third tier 300 in an abutting manner to the lateral surface of the blocks 402.
- FIGS. 13-17 Another embodiment of a corbel structure 500 is shown in FIGS. 13-17.
- the corbel structure 500 includes three tiers 600, 700 and 800 of blocks to be described in greater detail below.
- the courses 600, 700, and 800 collectively define central substantially vertically oriented flues 160 and lateral substantially diagonally oriented flues 172 which communicate with corresponding flues within the walls of the coke oven walls (not shown) to allow for the burning of air and gas therein and the transport of heated waste gas to and from the regenerator regions.
- the first tier 600 of the corbel structure 500 is provided with an interconnected series of cradle blocks 602 that are somewhat similar to the cradle blocks 102 of the corbel structure 10 as previously described.
- Each of the cradle blocks 602 defines a semi-cylindrical surface 604 extending longitudinally between the front and rear faces of each block.

The segments of the flue 160 defined by the crown blocks 704 are aligned with respective apertures 606c formed in the upper semi-cylindrical gun blocks 606a. Non-apertured filler blocks 706 may be provided as needed (i.e., where it is not required to provide a section of the flues 160 and/or 172).
- the crown blocks 702, 704 collectively define a semi- cylindrical surface 708 which conformably mates with the semi-cylindrical gun blocks 606a.
- the gun blocks 606 are thereby positionally captured between the crown blocks 702, 704 on the one hand and the cradle blocks 602 on the other hand.
- the crown blocks 704 may include a static gas nozzle 807 positioned in the segment of the flue 160 so as to control the flow of gas thereinto.
- the third tier 800 is comprised of an alternating series of inverted T-shaped lateral flue cap blocks 802 and inverted T-shaped central flue cap blocks 804, the former defining a section of the
- Lower spacer blocks 806 abut laterally against the side edges of the blocks 802, 804 and are supported by the upper lateral surfaces of the blocks 702, 704 of the subjacent second tier 700 of blocks.
- the blocks 802, 804 respectively define lower ledges 802a, 804a which are coplanar with the top surface of the lower spacer blocks 806.
- the upper spacer blocks 808 (see FIGS. 13-15) are thus supported by the lower spacer blocks 806 and have respective end portions which are received on the lower ledges 802a, 804a.
- configured non-apertured filler blocks 810 may be provided as needed (i.e., where a segment of the flues 160, 172 is not required).
- a series of elongate shoulder blocks 812 is positioned in an end-to-end manner on the upper ledge surfaces 802b, 804b of the blocks 302, 304, respectively, of the third tier 300 (see FIG. 1 1 ).
